PHP 7.1.0 Released

parse_ini_string

(PHP 5 >= 5.3.0, PHP 7)

parse_ini_string解析配置字符串

说明

array parse_ini_string ( string $ini [, bool $process_sections = false [, int $scanner_mode = INI_SCANNER_NORMAL ]] )

parse_ini_string() 返回 ini 字符串解析后的关联数组

ini 字符串的格式参考 php.ini

参数

ini

ini 字符串内容

process_sections

设置 process_sections 参数为 TRUE,得到一个多维数组,包含名称和设置。process_sections 默认为 FALSE

scanner_mode

可以是 INI_SCANNER_NORMAL (默认)或 INI_SCANNER_RAW 。如果是 INI_SCANNER_RAW,那么选项值不会被解析。

As of PHP 5.6.1 can also be specified as INI_SCANNER_TYPED. In this mode boolean, null and integer types are preserved when possible. String values "true", "on" and "yes" are converted to TRUE. "false", "off", "no" and "none" are considered FALSE. "null" is converted to NULL in typed mode. Also, all numeric strings are converted to integer type if it is possible.

返回值

执行成功返回一个关联数组,返回 FALSE 为失败

注释

Note: 保留关键字不能作为 ini 的键,包括 null, yes, no, true, false, on, off, none以及空值,off,no 和错误的结果集,值为 yes 和 正确的结果集。除非使用 INI_SCANNER_TYPED 模式。 字符 ?{}|&~![()^" 不能在任何地方使用作为键和有特殊意义的值。

parse_ini_string_m is analog for a parse_ini_string function.

had to code this function due to the lack of a php 5.3 on some hosting.

parse_ini_string_m:
- ignores commented lines that start with ";" or "#"
- ignores broken lines that do not have "="
- supports array values and array value keys

<?php
function parse_ini_string_m($str) {
   
    if(empty(
$str)) return false;

   
$lines = explode("\n", $str);
   
$ret = Array();
   
$inside_section = false;

    foreach(
$lines as $line) {
       
       
$line = trim($line);

        if(!
$line || $line[0] == "#" || $line[0] == ";") continue;
       
        if(
$line[0] == "[" &amp;&amp; $endIdx = strpos($line, "]")){
           
$inside_section = substr($line, 1, $endIdx-1);
            continue;
        }

        if(!
strpos($line, '=')) continue;

       
$tmp = explode("=", $line, 2);

        if(
$inside_section) {
           
           
$key = rtrim($tmp[0]);
           
$value = ltrim($tmp[1]);

            if(
preg_match("/^\".*\"$/", $value) || preg_match("/^'.*'$/", $value)) {
               
$value = mb_substr($value, 1, mb_strlen($value) - 2);
            }

           
$t = preg_match("^\[(.*?)\]^", $key, $matches);
            if(!empty(
$matches) &amp;&amp; isset($matches[0])) {

               
$arr_name = preg_replace('#\[(.*?)\]#is', '', $key);

                if(!isset(
$ret[$inside_section][$arr_name]) || !is_array($ret[$inside_section][$arr_name])) {
                   
$ret[$inside_section][$arr_name] = array();
                }

                if(isset(
$matches[1]) &amp;&amp; !empty($matches[1])) {
                   
$ret[$inside_section][$arr_name][$matches[1]] = $value;
                } else {
                   
$ret[$inside_section][$arr_name][] = $value;
                }

            } else {
               
$ret[$inside_section][trim($tmp[0])] = $value;
            }           

        } else {
           
           
$ret[trim($tmp[0])] = ltrim($tmp[1]);

        }
    }
    return
$ret;
}
?>

example usage:

<?php
$ini
= '

    [simple]
    val_one = "some value"
    val_two = 567

    [array]
    val_arr[] = "arr_elem_one"
    val_arr[] = "arr_elem_two"
    val_arr[] = "arr_elem_three"

    [array_keys]
    val_arr_two[6] = "key_6"
    val_arr_two[some_key] = "some_key_value"

'
;

$arr = parse_ini_string_m($ini);
?>

variable $arr output:

Array
(
    [simple] => Array
    (
        [val_one] => some value
        [val_two] => 567
    )

    [array] => Array
    (
        [val_arr] => Array
        (
            [0] => arr_elem_one
            [1] => arr_elem_two
            [2] => arr_elem_three
        )
    )

    [array_keys] => Array
    (
        [val_arr_two] => Array
        (
            [6] => key_6
            [some_key] => some_key_value
        )

    )

Replacement for php_ini_string() for PHP pre 5.3 - uses php_ini_file() and streams

<?php
if ( !function_exists( 'parse_ini_string' ) ) {
    function
parse_ini_string( $string, $process_sections ) {
        if ( !
class_exists( 'parse_ini_filter' ) ) {
           
/* Define our filter class */
           
class parse_ini_filter extends php_user_filter {
                static
$buf = '';
                function
filter( $in, $out, &$consumed, $closing ) {
                   
$bucket = stream_bucket_new( fopen('php://memory', 'wb'), self::$buf );
                   
stream_bucket_append( $out, $bucket );
                    return
PSFS_PASS_ON;
                }
            }
           
/* Register our filter with PHP */
           
stream_filter_register("parse_ini", "parse_ini_filter")
            or return
false;
        }
       
parse_ini_filter::$buf = $string;
        return
parse_ini_file( "php://filter/read=parse_ini/resource=php://memory", $process_sections );
    }
}
?>
